PURPOSE To elucidate factors related to ocular inflammatory attacks after cataract surgery, limited to a single procedure of phacoemulsification and intraocular lens implantation, in patients with Behçet disease. METHODS This retrospective study included 12 consecutive patients (16 eyes) with Behçet disease, who underwent phacoemulsification and(More)
Fluorescein angiography was performed to examine retinal vascular abnormalities in five consecutive patients with inflammatory bowel disease seen during the 2 years from April 1995 to March 1997, in a university hospital. All patients showed dye leakage from retinal capillaries in the peripheral fundi of both eyes. Other ocular findings included iritis in(More)
PURPOSE To elucidate clinical and angiographic features of retinal manifestations in cat scratch disease. METHODS Clinical characteristics as well as fluorescein and indocyanine green (ICG) angiographic features were reviewed in 4 consecutive patients with retinal manifestations caused by serologically confirmed cat scratch disease. RESULTS A subretinal(More)
The healing process in a wound induced by removal of 6 X 6 mm of gingiva and periosteum from the maxillary attached gingiva of 48 adult mongrel dogs was observed to investigate the potential blood supply for grafts placed on denuded bone. Three-dimensional observations were performed over 12 weeks by scanning electron microscopy (SEM) following the(More)
Most periodontal surgery has been performed on the basis of the regenerating capacity of the periosteum. Recently it has been pointed out that the blood supply is important to the osteogenic and fibrogenic activity of the periosteum. The purpose of the present study was three-dimensional observation of blood vessels distributed within the gingival(More)
PURPOSE The effect of mechanical stretching was examined on cultured scleral fibroblasts of the human eye in order to observe changes in their production of TIMP (tissue inhibitor of metalloproteinase)-1, MMP (matrix metalloproteinase)-1 and -2 in response to physiological strain. METHODS Human scleral fibroblasts were cultured from scleral tissue(More)
Nobuto has previously reported on the initial anastomosis involved in establishing circulation between a free gingival autograft and the recipient bed. This study will present observations on the maturation of new sinusoidal vessels involved in maintaining circulation to the graft and the resulting histovascular organization. Using 56 mongrel dogs, the(More)
The purpose of this study was to investigate the initial healing response of surgically flapped periodontal tissues in the presence of gelatine membrane compounded with particles of cementum. Four monkeys with no periodontal disease were used in this experiment. Full thickness flaps were raised and recession type defects were created on the buccal side of(More)
